How To Use Your Canner - Presto Pressure Canner and Cooker Instructions And Recipes Manual

6. Reinsert the overpressure plug by pushing the domed
side of the plug into the opening from the underside
of the cover, until the bottom edge is fully and evenly
seated against the underside of the cover (Fig. C). When
the overpressure plug is
properly installed, the
word (TOP) will be visible
on the overpressure plug
when viewing the outside
of the cover.
7. Replace the sealing ring in the sealing ring groove, mak-
ing certain to fit the ring under the stop tab located on the
inside rim of the cover (Fig. D).
8. The sealing ring is prelubricated; therefore, do not apply
cooking oil to it. If necessary, to help make the cover
easier to open and close, a very light coating of cooking oil
may be applied to the underside of the body lugs (Fig. E).
IMPORTANT: Never oil the sealing ring. Cooking oil
will swell and soften the sealing ring, reducing the usable
life and require frequent replacement. The cover should
open and close easily when following the instructions in
the next column (Fig. J).

9. Attach the dial gauge to the canner cover. To do this,
remove the nut and metal washer from the threaded end
of the dial gauge, leaving
the rubber washer in place.
From the top of the cover,
insert threaded end of gauge
through the hole in the center
of the cover, until metal base
rests on cover. While holding
the gauge in place, carefully
turn cover over and place
metal washer, then nut, on
threaded end of gauge and
tighten. (Fig. F).

How to Use Your Canner

IMPORTANT: Read carefully. Do not attempt to use your
Pressure Canner before reading these instructions.
 Before using your canner for the first time, clean accord-
ing to the instructions on page 2.

 Be sure the vent pipe is open
before each use by holding
the cover up to the light and
looking through the vent pipe
(Fig. G). If the vent pipe is blocked,
excess pressure cannot be released
through it. Pressure may then build
to unsafe levels. Pressure will con-
tinue to build until the overpressure
plug is forced out of its cover open-
ing. Therefore, clean the vent pipe
with a small brush or pipe cleaner
if it is blocked (Fig. H).
 The correct pressure for canning
and cooking is indicated by the
pressure dial gauge (Fig. I). Pres-
sure is indicated on the gauge
which registers the pressure inside
the unit at all times. The pointer
will move across the dial as pres-
sure is developed or reduced within
the canner. The pressure regulator
is designed to rock only at 15
pounds pressure.
 Do not strike the rim of the canner body with any cooking
utensil as this will cause nicks which may damage the
rim and allow steam to escape.
 Use the canner on a level burner and range only. Use on
a tilted burner or range may interfere with the operation
of the pressure regulator.
 Pouring water into a dry overheated canner may crack
the metal.
 The canner has been de-
signed so the cover will go
on in only one position and
rotate in only the directions
indicated for closing and
opening. Press down on the
cover handles to compress
the sealing ring and make
the cover easier to close.
The cover has the words
CLOSE V OPEN em-
bossed on the top surface
near a cover handle. Align
the "V" on the cover with the mark on the body handle
for proper cover and body alignment. Turn the cover in
the direction indicated to close until the cover handles
are centered directly above body handles. Do not rotate
cover beyond this point (Fig. J).
When the cover is rotated to the closed position, the air
vent/cover lock passes under the locking bracket. When
the handles are aligned, one over the other, the pressure
regulator is placed on the vent pipe, and heat is applied,
pressure will begin to build within the canner. At this
point, the air vent/cover lock lifts and locks the unit. The
cover will remain locked as long as there is pressure in
the canner. When pressure is completely reduced, the air
vent/cover lock drops allowing the canner to be opened
(Fig. K, next page).
